[Illusion]

I just finished the game last night, fought the FINAL FINAL FINAL boss, all my levels and jobs to max, and fought the super secret boss in the final hidden dungeon and killed him with ease (sitting on auto battle is and watching the guy get pulverized. He was so OP and yet the last boss was easier than him, and all his immortality goodness.)
Oh yeah and the secret ending to the game <3 best use of the 3DS's VR and gyroscope yet! Makes me excited for the games sequel.
Oh and if you don't want to wait until you beat the game all the way through for the secret ending like I did. Just use the konami code and apparently it will instantly take you the games secret ending. (There are no spoilers truly in it though as you have no idea why the thing that's happening in the secret ending is happening.)
